LIQUID-DISPENSING APPARATUS.

Application filed December 10, 1925. Serial No. 74,570.

This invention relatesto devices for dispensing liquids particularly adapted for use in. the retailing of gasoline and the like, and my object is to produce apparatus for this purpose oi. the type in which the liquid is dispensed from an'ieasuring chamber in which the liquid is visible; in which the measuring chamber is readily repaired or replaced; in which the dispensing apparatus is readily adjustable to accurately draw oil desired quantities of liquid; and in which the shape of the chamber and the construction and arrangement oi? the dispensing mechanism are so related that the chamber may be made cl :1 inininuini cross sectional area relative to its height for the type of dispcnsin mechanism employed.

ll attain my object by forming the 1neastiring chamber ojl rectangular itorin in horisontal cross section, and providing it with one or more ro ilaceafble gl ass sides.

The dispcni-iinjz means includes a drawoilj tube journalled at the bottom of the measuring chamber adjacent one corner and adapted to swing in a vertical. plane diagm nal to the sides oi? the chamber.

t top mechanism is n'ovided whereby the draw-oil tube may be positioned to draw oil any desired quantity of liquid, and this stop mechanism is provided with separate adjusting means For each position whereby absolute accuracy of measurement may be attained at any predetermined position of the draw-off tube.

'llheinvention is illustrated in the accon'n panying drawings in which i. lg. 1 is a horizontal section through the measuring chamber of a dispensing device constructed in accordance with my invention;

Fig. 2 a vertical section along the line B-Q in 1, parts being broken away;

Fig. 3 a sectional detail. illustrating the operating means for the draw-oil tube of the adjustable stop mechanism therefor; and i Fig. 6% a plan view of the adjustable slide on one oi the stop mechanisms in the drawings like numerals of referencc indicate corresponding parts in the different figures. j

l are standards on which aresupported the corner :lraines 2 of the measuring chamher. In the preferred construction these standards are formed as rods having their ends threaded into the sleeves 3 forming parts of the corner frames. The standards 1 will, o'tcourse, be supported on any suitablebase (not shown). The corner frames are tin-med with flanges against which the glass side plates 41: are clamped by means of the rabbeted frames 5, suitable packing or luting being employed. to make the joints liquid tight; A suitable cover 6 is provided ior the chamber. The bottom of the chamber underlies the corner frames 2, which latter are held securely in position relative to the bottom by the standards 1.

In the bottom of the chamber isiornied a recess 8, the said recess extending substandischarge tube 12, which sleeve isi'uounted in the side wall of the recess 8. The drawoil' tube is thus adapted to be swung up and down to bring its mouth to different levels in the ineasiiring chamber whereby any desired quantity of liquid may be drawn oil.

To operate the draw-oil tube I provide the following mechanism. A spindle 13 is secured to the draw-d tube andextends anially through the trunnion and sleeve 11, passing out through theiouter end of the latter through a stullingbox 14. Arockarm 15 is secured to the end of this spindle. A spring 16 bearing against the endof the stufling box and against the rock arm provides means tendingto maintain the tubular trunnion in its position in the sleeve 11. The rock arm is provided with means whereby it may be locked in any desired position to thus rigidly fix the position of the draw-oil tube. It is essential that the stop mechanism be adjustable and that separate adjustment be provided for each position of the draw-oif tube, since it is not commercially racticable to make these measuring chain ers absolutely true and the draw-oil mechanism must be capable of being separately adjusted for each position according as one, two, three four, five or more gallons of the liquid are .to be drawmoif. I therefore provide the cross section of the chamber, the horizontal cross sectional area of the chamber being less than the square of the length of said tube and its height at least equal to the length of the tube less the distance of its pivot below the bottom of the chamber.

5. Liquid dispensing apparatus comprising a chamber; a draw-oil tube journalled to swing in a vertical plane Within the chamber; operating means for the tube outside the chamber including a rock arm; a plate over Which the rock arm is movable; a slide movable on the plate in a direction substantially normal to the arc in which the rock arm swings; a slot being formed in the slide inclined to the direction of movement of the slide and also inclined to the direction of movement of the rock arm; means for clamping the slide; and a retractible pin on the rock arm engageable in the slot in positions therein varying with the positions of the slide.

INSECTICIDE AND FUNGICIIDE.

No Drawing.

This invention relates to improvements in insecticides and fungicides, and more particularly to insecticides and fungicides suitable for the treatment of seeds and plants.

5 In accordance with the present invention the improved composition comprises a mineral oil, a salt of sulfonic acid derived from mineral oil and an'oil-dispersible copper derivative, and is capable of forming a stable l emulsion with water which is suitable for ap plication to plants and seeds for insecticidal and fungicidal purposes.

It is preferred to employ as the emulsifying compound the so-called mahogany l soaps or alkali-metal salts of preferentially oil soluble sulfonic acids derived from mineral oil in the manner described in the Humphreys U. S. Patent No. 1,286,179 granted November 26, 1918, or in any other suitable manner. As the copper compound it is preferred to employ the corresponding cop er sulfonate or copper sulfonates of the preferentially water-soluble sulfonic acids, derived from mineral oils in the manner described in Patent No. 1,474,933, granted November 20, 1923, to Humphreys and others, or in any other suitable manner; or we may employ the copper salt of naphthenic acids, for example, the naphthenic acidsderived, 30 as soaps, from coastal or other crudes Which contain them, by treating a lubricant distillate thereof with alkali and extracting with alcohol.

The improved product preferably contains about 8 to of the emulsifying agent about 10 to of the popper compound and about 4:5 to $707}; of mineral oil. The mineral oil employed is preferably a light mineral oil heavier than gasoline, as kerosene, straw oil or the like.

Although it is preferred to employ such copper compounds as are herein named, and which are particularly adapted for .the production of freely emulsifiable compositions efficient in use, other oil dispersible copper derivatives, as the copper salts of organic acids, particularly of the fatty acid type (e. g. copper cleats} or the copper saltv of mahogany acids may be employed.

The invention will be more fully appreciated from the following examples of pre ferred compositions, but it must be understood tic these examples are illustrative only at that the invention is not limited thereto, since the invention comprises innum- Application filed May 3, 1926.
